So I am installing a shift kit and was watching some youtube videos trying to learn more about what different servos and valves do and saw that there are supposed to be two small filters in the case under the valve body, one in the front and another at the rear. I did a search but everything comes up for the big square main trans filter, maybe there is another name for the two small ones? My trans was rebuilt and I do not see any filters where the arrows in the attached pic point to. Is this fine and most people leave them out, or do I need to source and install these before I bottom it back up. Also what are they they to protect, pieces of clutch material or whatever coming from the trans above the VB?
